ITXC Corp. (NASDAQ:ITXC)

    --  Connection to ITXC's global network gives Intelig immediate
        revenue from incoming worldwide traffic

    --  Intelig now is able to send calls to any destination in
        the world over ITXC's network

Intelig, Brazil's second largest international long distance carrier, and ITXC Corp.(R) (NASDAQ:ITXC), one of the world's leading international voice carriers, announced today that they are exchanging international voice traffic to and from Brazil over ITXC's global network.

Through its relationship with ITXC, Intelig receives payment from ITXC for completing calls in Brazil that ITXC aggregates from carriers around the world. In addition, Intelig is leveraging ITXC's high quality, low cost call completion to countries around the world, enabling them to aggressively compete in the growing Brazilian internal long distance market.

Intelig enjoys these benefits without additional capital investment.

"Our connection to ITXC's global network allows us to receive a new revenue source while lowering costs so that we can focus on continuing to win market share in Brazil," said Leila Garcia, Carrier Services Director at Intelig. "We are not only completing calls for ITXC, we are also using their network to send long distance calls around the world in a more efficient and cost-effective way."

"By connecting to ITXC's global network, Intelig receives international call quality that meets the needs of their retail and enterprise customers in one of the largest emerging telecommunications markets in the world," said ITXC Chairman and CEO, Tom Evslin. "We are pleased to enable Intelig, one of the major carriers in Brazil, to continue to reap the benefits of liberalization of the long distance market in Brazil."

ITXC has been expanding its presence in Latin America with recent appointments of Country Sales Managers in Brazil, Argentina, and in Chile. This expansion is evidence of the company's plans to strengthen and grow ITXC's relationships with all major licensed carriers in Latin America.

The international long distance wholesale business in Latin America is expected to grow from 1 billion minutes of use in 2001 to 15.4 billion minutes in 2007, according to a Frost & Sullivan's Latin America market study.
